'Atlantic Ocean Floor'
This compelling map presents the Atlantic seabed as a continuous mountain landscape. In the 1950s Marie Tharp and Bruce Heezen assembled depth soundings into the first coherent scientific picture of the Atlantic floor. Tharp’s identification of the rift valley along the Mid-Atlantic Ridge supplied powerful visual evidence for seafloor spreading and helped move geology towards acceptance of continental drift and plate tectonics. Issued by National Geographic in 1968, this is not one of those original pioneering maps, but a later, exceptionally effective interpretation of their research. Heinrich Berann’s painterly shaded relief turns measurements into an illuminated terrain of ridges, abyssal plains, fracture zones and continental margins: both scientifically eloquent and visually beautiful. A conventional annotated map of the Atlantic Ocean is printed on the reverse.
